Abstract :
In this paper, the authors propose a method to obtain the compensation signal to suppress the vibration of the. motor frame by the repetitive control installing an online Fourier transform and utilizing an acceleration sensor attached to the motor frame or an acoustic sensor (microphone) detected by a microphone placed close to the motor frame. The sensor is used only for the acquisition of the feedforward compensation data. Also presented is a new method of the feedforward compensation control adapting to change of operating point of the motor. The effectiveness of the proposed method is confirmed by experimental results.
